System Components: 10base-T

Most Ethernet wiring uses ordinary twisted pair phone line to transfer data within a LAN. The designation, 10base-T is an Institute of Electrical and Electronics Engineers shorthand. "10" refers to the transmission speed of 10Mbps (megabits per second). Base means that only Ethernet signals are carried on the line. "T" represents twisted pair. There are other media used to transfer Ethernet signals that can use coaxial cable or fiber optical cable.
